Mkuu, i think capitalism, with a bit of socialism in managing it, is optimal..the anarchy of both is deadlier. The Social part of it, is important because of our level of development, so that it can't breed the the primitive wealth accumulators of Moi, Biwot, Matiba, Kenyatta, Mkapa, Rostam and Lowassa type. Please Read: The Age of Turbulence (a good masterpiece btw) by Alan Greenspan, though was a chairman of the fed himself, he admits you need a bit of socialism even in developed economies. But still capitalism is a trigger and an a engine of economic growth. Kenya's i think, was a primitive capitalism, that's why majority of them are still poorer than the former socialist Tanzanians. Without capitalism, the existence of capital owners, everybody will be a boss, nobody will work..you know the outcome!
I challenge you to prove that!!
